IMPROVEMENT lN MODE OF SECURING BOBBINS IN SHUTTLES.

To all whom it may concern Be it known that I, S. C. MENDENIIALL, of Richmond, in the county of Wayne and State of Indiana,have made new and usefulmprove ments in the Mode of Fastening Bobbins in Shuttles; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same,sufiicient to enable one skilled in the art to which it appertains to construct and use the same, reference being had to the accom pany ing drawings, which are made part of this speciiication, and in which- Figure l is a plan view of the shuttle. Eig. 2 is a plan or top View ot' the bohbin. Fig. 3 is an end view of the bobbinhead.

Similar letters of reference denote the same parts.

rIhe improvements in the shuttle and bobbin are as follows: first, the peculiar form of my bobbin-head; second, the manner of locking the bobbin in the shuttle.

A is the shuttle. B is the bobbin. C is a wire or rod which locks the bobbin in the shuttlc, and the red dotted line I represents a slotted or spring spindle for the bohbiu, and which, by reason of a slight outward spring tendency, serves to hold the bobbin with suiicient steadiness.

Fig. 2 shows the form of the bobbin. H is the head, which is turned with a groove, O, in it. S is that portion outside the groove a segment of which is cnt away to thedepth of the groove.

Fig. 3 is an end view ofthe bobbin-head; S a segment of the same removed to the depth of the groove, and which may extend to any portion ofthe entire circumference ofthe bobbinhead.

I do not connc myself exclusively to the wire or rod C, as above described, as a plate could be secured ou the top of the shuttle with a right-an gled projection extending downward to the saine depth as the wire or rod, and therefore answer the saine purpose.

lith theforegoing description of the shuttle and bobbiu the mode of locking the bobbin in the shuttle is very simple. The bobbinisplaced iu the shuttle from the top side and pushed back on the spindle till the dat side S passes under the wire or rod C; then by giving 'the bobhiu a slight turn with the thumb and iinger it is efIectna-lly locked. The head of the bobbin is slightly corrugated, so as to facili tate the operation of turningit around in order to lock it, as ahove described.

Havingdescribed myinvention, what I claim as new, and desire to secure by Letters Patent, is-' The bobbin, having its head constructed as described, in combination with the wire or rod C in the shuttle, all as and for the purpose set forth.
